Abstract

Selon des modes de réalisation, la présente divulgation se rapporte au domaine technique du traitement informatique de données. Un procédé et un appareil de traitement de message, ainsi qu'un dispositif, un support et un programme sont divulgués. Le procédé consiste : à acquérir un emplacement d'indice cible correspondant à un client cible sous un thème cible, le client cible étant un client s'abonnant au thème cible ; à interroger, en fonction de la position d'indice cible, un fichier d'indice de message correspondant au thème cible, de manière à obtenir un emplacement de message cible, le fichier d'indice de message comprenant la correspondance entre une pluralité d'emplacements de message correspondant au thème cible et une pluralité d'emplacements d'indice ; à interroger un fichier de stockage de message en fonction de l'emplacement de message cible, de manière à obtenir un message cible, le fichier de stockage de message comprenant une pluralité d'emplacements de message correspondant à une pluralité de thèmes, un message correspondant à un thème étant stocké à un emplacement de message, et le thème cible étant un thème de la pluralité de thèmes ; et à envoyer le message cible au client cible. Selon les modes de réalisation de la présente divulgation, au moyen du procédé ci-dessus, l'efficacité de traitement de message peut être améliorée.
